Definitions
- the present invention relates to a method for the hydrogen passivation of semiconductor layers, to the processable passivated semiconductor layers and their use.
- semiconductor layers may have so-called dangling bonds in the semiconductor structure.
- the semiconductor characteristics can be degraded.
- this can lead to a reduction of light-induced charge transport.
- hydrogen can be introduced into the semiconductor layer, in particular after the production of the layer. This entry of hydrogen is called hydrogen passivation.
- Document EP 0 419 693 A1 describes a hydrogen passivation of silicon by a temperature treatment in a hydrogen-containing atmosphere. Preferably, temperatures of from 250 ° C to 500 ° C are used. However, the process described there is very expensive in terms of apparatus.
- the document US 5,304,509 A discloses that a silicon substrate can be passivated with hydrogen by first treating the silicon substrate with a hydrogen ion beam on the back side and then irradiating (front side) with electromagnetic radiation. After the treatment with the hydrogen ion beam, the implanted hydrogen ions quickly diffuse through the substrate and then lift the defects that have occurred after the irradiation.
- US 4,343,830 A describes a method for passivation of polycrystalline silicon solar cells, in which a high-pressure hydrogen plasma (preferred pressure 760 Torr) is used.
- a high-pressure hydrogen plasma (preferred pressure 760 Torr) is used.
- the advantage is that generation of the plasma at low pressure is no longer necessary, but the disadvantage of the high-pressure hydrogen plasma used there is that the apparatus complexity is also very great here in that radio frequency generators and impedance units must generally be used to generate the high pressure hydrogen plasma.
- US Pat. No. 6,330,397 B1 describes a method which is very complex in terms of apparatus for treating thin layers with an inductively coupled plasma. Furthermore, the method described there is not suitable for a good hydrogen passivation of semiconductor layers. In contrast, it is now the object of the present invention to avoid the disadvantages of the prior art. In particular, it is the object of the present invention to provide a low-complexity process for the hydrogen passivation of semiconductor layers, which does not lead to damage of the substrate or the semiconductor layers deposited thereon, which can be applied in a continuous process and which leads to a particularly good passivation leads.
- the method according to the invention for the hydrogen passivation of semiconductor layers, in which the passivation takes place by use of an arc plasma source.
- the method according to the invention moreover has the advantage that the method can be used under atmospheric pressure and is very economical.
- a method for the hydrogen passivation of semiconductor layers in the context of the present invention is understood to be a method for saturating the already mentioned open bonds located at the locations of the defects, generating atomic hydrogen at the respective location of the defect at the surface and in the surface Is transported inside the semiconductor layer, wherein the atomic hydrogen then saturates the respective open (s) bond (s).
- Hydrogen passivation for example, is measurable for solar cells by increasing light-induced charge transport relative to the time before passivation.
- the hydrogen passivation can be checked by IR spectroscopy by changing the bands of the respective semiconductor (for silicon layers: by changing the characteristic band at 2000 cm -1 ).
- a semiconductor layer is to be understood as meaning a layer which comprises at least one element semiconductor, preferably selected from the group consisting of Si, Ge, ⁇ -Sn, C, B, Se, Te and mixtures thereof, and / or at least one compound semiconductor, in particular from the group consisting of IV-IV semiconductors such as SiGe, SiC, III-V semiconductors such as GaAs, GaSb, GaP, InAs, InSb, InP, InN, GaN, AlN, AlGaAs, InGaN, oxide semiconductors such as InSnO, InO, ZnO, II-VI semiconductors, such as ZnS, ZnSe, ZnTe, III-VI semiconductors, such as GaS, GaSe, GaTe, InS, InSe, InTe, II Il-VI semiconductors, such as CulnSe2, CulnGaSe2, CulnS2, CulnGaS2, and mixtures thereof, or consists thereof.
- IV-IV semiconductors such
- the semiconductor layer to be passivated is a silicon-containing layer, i. around a substantially pure semiconductive silicon layer, a u. a.
- a silicon-containing compound semiconductor layer or a silicon-based, moreover containing dopants layer is a silicon-containing layer, i. around a substantially pure semiconductive silicon layer, a u. a.
- the silicon-containing semiconductor layer is a silicon-containing layer, which was produced thermally or with electromagnetic radiation substantially from liquid hydridosilanes.
- the arc plasma source to be used according to the invention is a source for a plasma generated by a self-sustaining gas discharge between two electrodes having a sufficiently high electrical potential difference, in which the gas used has at least one hydrogen source. Corresponding plasmas have temperatures of ⁇ 3000 K.
- Preferably used arc plasma sources since in them the formation of the arc plasma outside of the actual reaction zone and then the plasma at a relatively high flow rate and thus can be quickly directed to the surface of the substrate to be treated, whereby the plasma formation is not affected by the substrate and a high Process reliability results are those in which the plasma is generated by a high-pressure gas discharge at currents of ⁇ 45 A.
- a gas discharge at pressures of 0.5 to 8 bar, preferably 1 to 5 bar is to be understood as meaning a gas discharge under high pressure.
- manufactured plasmas have the advantage that they are potential-free, and therefore can cause no damage of the surface by discharge. Furthermore, no foreign metal entry takes place on the surface, since the substrate does not serve as an antipole.
- the discharge takes place between two electrodes, the anode and the cathode.
- the cathode can be specially designed.
- Preferred plasma generators operate at a square wave voltage at 15-25 kHz, 0-400 V (preferably 260-300 V, in particular 280 V), 2.2-3.2 A and a plasma cycle of 50-100%.
- Corresponding plasmas can be produced, for example, with the arc plasma sources available under the commercial product designation generator FG3002 from Plasmatreat GmbH, Germany or under the commercial product name Plasmabeam from Diener GmbH, Germany.
- the arc plasma source in the method according to the invention is preferably used such that the nozzle, from which the plasma exits, at a distance of 50 ⁇ to 50 mm, preferably 1 mm to 30 mm, particularly preferably 3 mm to 10th mm away from the semiconductor layer to be passivated. If the distance is too close, the energy density is too high, so that surface damage to the substrate may occur. If the distance is too far, the plasma breaks down, so that no effect or only a small effect occurs.
- the arc plasma source has a nozzle from which the plasma exits.
- nozzles for the arc plasma source are pointed nozzles, fan nozzles or rotating nozzles, wherein preferably pointed nozzles are used, which have the advantage that a higher point energy density is achieved.
